PRINTING Pnoonss.

To all 'whom 'it may concern.: l

Be it known that l, FELIX Knonnn'r, asubject of the German Emperor, residing at Halle-on-the-Saale, in Germany, have invented certain new and useful Improvements in Printing Processes, of which the following is a specication.

This invention relates .to new printing recesses which allow, for example, of proucing granulated prints on a smooth shining background, or shining prints on a dull or granulated background. In addit-ion, pastel painting can be edectively imitated by means of this process, and also woven fabric, embroidery, lace, network, knitting, gobelins and the like. Prints made on metal plates by this process are particularly suitable for advertisements. l y The annexed drawing illustrates several methods of carrying this invention into e'ect, it being understood that the illustrations represent greatly magnified sections (but not to scale) iii-order that the nature of the structure may be more easily explained. u

Figure l illustrates a plate treated with a Whole surface coating of granular material. Fig. 2 illustrates the same colored as in pastel painting. yllig. 3 illustrates a design in granular material on a plain background. Fig. t illustrates a raised granular design on a granular background. Fig. 5 illustrates a raised design on a plain colored According to this yinvention the surface A on which the print is to be made, that is, the surface which is to carry the picture, tent or design, is covered' in whole or in part with an adhesive B on which is thrown a granu` larsubstance, itor example, wool-dust, wood dust or the like represented by C, so that itis attached. to the surface by the adhesive B as in Fig. l. 'lo givethis rough coating a better permanency and to allow of printing upon it, it is coated with 'varnish or lacquer D when dry.l lf the granular substance is to Jform a design, the Aadhesive is applied as at B2, llig. 8., by means of a plate or cylinder, on which the type or design is arranged, and the granular material C2 is sprinkled over the surface while the latter is still moist. lt only the lbackground is to ,be rough, while the text or design is smooth,

` the printing is performed with a plate bearingonly the background, uand the dust is then sprinlded on as described. When the Specification of Letters Patent.

surface hasbecome dry the excess of owder is swept or brushed oft or removed y tapping or the like, and the whole can be varnished as at D2. u

For imitating or reproducing pastel painting the entire surface A1 '-(Fig. 2) of the work is coated with adhesive B1 and granular material C1 thrown thereon. When dry the surplus granular material is removed. Various colors are then printed in the usual order of succession as in multicolor printing. @wing to the rou honing of the surface by the granular powder no continuous surface is offered to the particles of color, so that the color only appears in the form of small points E close together, and thus imparts an appearance similar to that-of a pastel. D1 represents a surface coating of varnish over all. A

In imitating textile material, the irregularities or roughness peculiar to the original can be accurately reproduced. For this purpose the adhesive is applied as at B2 (Fig. 3) by means of a stone, plate or cylinder on which the pattern has been produced inthe usual manner. A colored 'or colorless adhesive substance, for example varnish may be used. Such pattern, executed in colored or non-colored adhesive substance, may be laid on conveniently in practice by' means of impression in a double cylinder power press, orin the case of sheet metal printing with a rubber cylinder, or it may be applied as The powder C2 is then applied, the superfluous powder being removed when the surface is dry.

'lhe layer of powder is coated when dry with varnish or lacquer D2 and so prepared for another application of color E2. The unevennesses due to the granular material exactly correspond with the unevennesses of the pattern, which therefore agrees with the original not only in color but also with regard to its raised and recessed parts. To increase theresemblance the operations oit printing in `adhesive powdering and varnishvarnishings are represented by C4, Dt, C

D40, Figari, and a final coloring by Et and coat ot varnish .over all by D400. If the unevennesses. are irregular, there being, for

example, larger protuberances at certain layer C4. lt is preferable to print with` color before the larger protuberances are formed, 'the latter being either separately printed or colored by applying colored powder. In order that the background is not visible between the raised parts, or at least does not shine through, the ,entire surface may, before the first printing, be uniformly coated with adhesive as at B3, powdered as C3, and varnished as D3, the pattern being ,then printed on the varnished surface as above mentioned and illustrated in'liig. el. Instead of a powdered background, a col cred covering layer may oi course be used as E4, Fig. 5. The color-printing on the uneven surface may be performed with" a plate on which the picture is continuous, or to increase t-he eiiect the picture may be previously divided to agree with the unevein nesses.

The process of separately color-printing the relief portions, of different heights, oi:r

the uneven design may either be eliiected by color-printing the ground (as in F ig. 5), then applying the powder, and then printing on the powder, or the varnish layer is color-printed before the powder layer G4 is applied. In the latter case the printing of the varnish layer may only be partial,

e., the color being only applied to those parts to which no powder is to be applied, ,the printing being effected, for example, by the method commonly adopted in multicolor printing. The color pattern may also be produced by applying colored fiber-powder. A multitude of eii'ects can be produced by use of this granular powdered substance in the production of placards and posters. This is more particularly the case with sheet metal placards. The advertisements either in writing or pictorial,.may be matte on a glazed or polished background, or glazed on amatte background, and particular parts thereof may be brouglitinto special prominence. This is of special value lor the easy reading of the advertisement. Owing to the subsequent'coating of the surface' with varnish the metal may be bent, stamped., einbossed or otherwise treated without injuringthe layer of powder.

What I claim as my invention and desire to .secure by Letters Patent of the United States isr A pril ting process lfor producing raised granulated color prints, consisting in applying to a surface an adhesivesubstance, dusting the saine with a pulverulent, granular material, applying additional layers of adhesive to certain parts to produce an uneven design, dusting said additional layers with the pulverulent, granular material, vars nishing the whole, and separately color print!v ing the relief portions of different heights, ot the uneven design.

In 'witness whereof 1 have signed this specieation in the presence of two witnesses.
